Puisne judge

Puisne judge and puisne justice are terms for an ordinary judge or a judge of lesser rank of a particular court. The term comes from a combination of the two French words, puis, "since, later" + né, and "born", which have been combined as puisné or puîné; meaning "junior".

Use
The term is used almost exclusively in common law jurisdictions: the jurisdiction of England and Wales within the United Kingdom; Australia, including its states and territories; Canada, including its provinces and territories; India, including its states and territories; Pakistan, its provinces, and Azad Kashmir; the British Overseas Territory of Gibraltar; Kenya; Sri Lanka; South Africa in rural provinces and Hong Kong. In Australia, the most senior judge after a chief justice in superior state courts is referred to as the "senior puisne judge".

Use is rare outside of, usually internal, court (judicial) procedural decisions as to which judge(s) will sit or has sat in hearings or appeals. The term is dated in detailed, academic case law analyses and, to varying degree direct applicability in higher courts.

The term excludes the court's chief judge(s)/justice(s); any seniormost judges, often specialists or a managerial head, sitting ex officio (by virtue of their office) as such in the court for which they have duties below; and any technically junior judges who may have been called to serve in a higher court, whom law reports and transcripts customarily specify as "sitting in" a judicial panel of a higher court or "sitting as" a judge of that court.
